Proper Paver Selection

Paver selection can be overwhelming, to say the least.  We will try to untangle to the web of questions you will need to ask yourself prior to signing any pavement contract.

When I meet with homeowners, nine times out of ten they have already selected a concrete paver that they would like to have us install.  Some contractors blindly agree and put a cost together for the project using this paver.  We, on the other hand, like to pause and walk the homeowner through some important considerations to factor in prior to settling on a paver choice. Typically we start from the bottom up as detailed below.

1. Does the site require a certain type of paver or base?

Each site is unique, and therefore should be addressed as such.  We NEVER quote any job on a square foot basis for this reason. First, we analyze the site to determine if there is a requirement for the use of permeable pavers.  An example of such a site would be an area of the project that is continually plagued with water issues or has a soil grade that would inhibit surface draining water when using a standard paver. This also helps us to determine whether we would use a densely graded base (traditionally used on standard pavers), or an open-graded base (used in our permeable systems). See this difference below.

 

2. Determining application

It is important to determine the overall function of the area.  Will this area be used for pedestrian traffic or vehicular traffic?  If it is subject to vehicular traffic, then what is the Gross Axle Weight Rating (GAWR), or weight, of the vehicles that will be running over the paver?  This is immensely important as it relates to the depth of the base that is required, as well as the size of the paver being used.  Elegant Estates can take this information and calculate what depth of base is required based on the type of base being used, as well as what geotextile is required for the subgrade.  Answering these questions also comes into play when choosing a paver size. Professionals in our industry refer to a paver’s aspect ratio when determining its usefulness.   What is aspect ratio?  Aspect ratio is the relationship of its overall strength relative to its length and height.  Essentially, the wider and longer a paver is made, the thicker they need to be in order to bear heavier loads. Keep in mind that you should factor in the worst case SAWR.  For example, if you are planning to have a paver driveway installed then you need to ask yourself questions like this – My home has a septic system, so I will need to have that tank emptied from time to time. How heavy are those trucks?  Not only that, you need to know that they will be a lot lighter when they show up, and tons heavier when leaving your driveway. When you, or your contractor, fail to factor these variables into the base equation it will lead to a failed base and overall rutting of your pavement.

3. Now to the fun part – paver selection!

Now that you have narrowed down the choices of paver based on the type of paver you need (permeable vs. standard paver), the type of base you will need (open vs. densely graded), and purpose of the pavement (in order to verify the proper size required), you can move on to identifying the “look” that you want.  There is still a multitude of choices left to wrestle though including, but not limited to shape, color, and texture, as well as design questions relating to the overall appearance of your project.  It is important to familiarize yourself with certain terminology when it comes to pavers and designs. This will be covered more in length in future posts.

How NOT to get burned by your contractor’s hardscape bid!

We get called to design and submit a hardscape bid on plenty of projects each year, both large and small. In an effort to become a better company when we lose bids I always like to ask our leads where we fall in line with the competition cost-wise.  It never ceases to amaze me when I ask specific questions that directly impact the price, to hear what kind of answers I get.  It often goes something like this –

Me: How did we fall in line cost-wise with the other hardscape bids that you received?

Homeowner: You were 20% more than the one we ended up choosing.

Me: I would like to ask a few questions on what they bid for you.  Is that alright?

Homeowner: Sure.

Me: How much base material did they quote for you?

Homeowner: They didn’t say how much they would use.

Me: My notes show that you were interested in a curvilinear design.  That will lead to 5-10% extra stone waste.  Do you know if that is accounted for?

Homeowner: I don’t know.  I just got a total figure for the job.

Me: Okay, did they detail what was going to be done on the project?

Homeowner: No, the quote says they will be installing a walkway and patio with plantings.  Total cost – $25,000.

Me: Did they reference the design number?

Homeowner:  There wasn’t a design done.

 

Do you see where this is heading? THE. HOMEOWNER. GETTING. BURNED.  Well, not always, but why chance it?  I’m always floored to see how many people are willing to risk their hard earned money on a contractor’s hardscape bid scribbled on a napkin or college ruled stationary. When the costs of larger outdoor living spaces range in price which rivals that of a new car to as much as a modest size house, why not require more detail in the bidding process?

Take the car example; how many pieces of paper did you need to sign in order to drive that new Toyota Camry off the lot?  What about the last time you signed off on your mortgage.  Yeah, we all know how much fun those closings are!  The point being, it is okay to ask for project details to be specified in the contract.  Any pushback from the contractor on this request should raise large red warning flags.  A detailed contract serves to clearly communicate the intention of the contractor, and verify that it aligns with your wishes.  It protects both parties!

For the purposes of this article, I will take a paver installation project.  It should not be out of the ordinary to show the following information:

GENERAL INFORMATION (Minimum):

  • Insurance- Type of insurance and verification if necessary.  Do not hesitate to ask for a certificate of insurance and to contact their agent to verify that it is still an active policy.
  • Certifications-  Is the contractor certified in this field of work?  (ICPI for pavers or NCMA for walls)
  • Experience- Has the contractor done this type of work before, or are you the guinea pig?
  • Payment- How is the project going to be funded?  Is there a 50% down, 50% upon completion?  A down pay with progress payments? Regardless of the payment structure agreed to, it should be listed.
  • Timeline- When is the project going to be started and approximate date of completion?  It is not uncommon for contractors to over promise and under deliver in order to get a quick signature.  Furthermore, let’s be realistic – the weather is a huge variable so completion times should include some flexibility for weather delays and manufacturers issues.
  • Design– Was there a design done?  If so, it should be referenced if multiple revisions were submitted. If no design was done, how do you know you will be getting what you asked for?  Now, that being said, we do some installs at Elegant Estates without designs BUT we make it stated very specifically in the contract what we will be doing and how it will be installed before the homeowner signs off on it.  This is a process, and you should not feel rushed. Here is a typical design we do in-house for some medium-large projects that we install –

Paver Design as part of a hardscape bid

JOB SPECIFIC INFORMATION (Minimum):

  • How deep will the excavation be?
  • Will underground utilities be marked out?
  • Will geotextile be installed?
  • How much base will be installed?  What type, and how will it be compacted?
  • What kind of setting bed will be installed?
  • How much over-excavation will there be for edge restraints?
  • What kind of pavers will be used?  Color? Laying pattern?  Borders?
  • What kind of edge restraints will be installed?
  • What will be used in the joints between the pavers?
  • Does the project include cleanup?
  • Will the grading be done after work is complete?
  • Will the grass be reseeded where damage/grading is done?

Whereas the lack of general contract information can lead to overall general problems for you on a contractor & liability level, the lack of job information can come back on you in a financial sense due to change orders mid-stream, and worse yet the failure of your project or delivery of a result that you never originally wanted!

So, the next time you seek a contractor to do anything at your home, ask for a detailed hardscape bid.  You’ll thank yourself later!

 

Why do they call it hardscaping?

I giggle occasionally when I think of myself first getting into the landscape business back in 1999.  I recall going out on design consultations and speaking to clients about their project.  I would talk about how their house lends itself to, say, a modular design.  I would talk about softscaping and which types and sizes of plants we would use, the color of mulch, etc.

Then I would then say “now let’s talk about the hardscaping”.  I would guess about 90% of the time I would be looked at as if I was from outer space.  I would then respond with some contractor humor “you know, its the hard part of the job”. Being sort-of a landscape industry insiders joke, some prospects got it while others not so much.  Being a proud father of 4 children (3 of them girls), I was reminded the other day of the “hard” nature of our daily work in this video and I could totally see my girls pulling this stunt…

Knowing that each one of those real pavers in that clip was approximately 15 pounds each, you can sympathize with the folks on the receiving end of this prank!

True, hardscaping is indeed hard work and deals with more than just boulders, pavers and retaining walls. It’s work that can be done by the above average DIY’er if they have the spare time, the right equipment, and choose to follow the proper steps along the way.  Having the right equipment certainly helps make the project less “hard”, but not everyone has thousands of dollars to rent machinery.

We plan to have future blog posts relating to what kinds of things to look for when either choosing a contractor for your landscape and/or hardscape project, learning how to speak hardscape jargon, as well as how you can avoid common mistakes when installing your hardscape projects.
